Safari Content Blockers crash if the blocker list is too large

[saagarjha]

Seems to be a bug in the content blocker loader. Anyone not experiencing this problem?

[azinicus]

I think this is the same issue being experienced by similar project rocketshipapps/adblockfast#26

[saagarjha]

Yes it looks like it. I'm not sure if it's a bug with the CSS or SFContentBlockerManager, since all I get is a crash log.

Although it seems from my brief testing that the .json from this project actually blocks things whereas the AdblockFast one does not currently initiate by iOS (that one is much larger btw)

[saagarjha]

This was the most complex one that seemed to work.

Safari is meant to handle up to 50K rules, so your list is unlikely too big. In the case of Adblock Fast, I introduced a syntax error that Safari was failing silently on.

[saagarjha]

That might be it. I'll have to look into it.

Interested where the number 50K comes from

[saagarjha]

I believe this number has been increased recently, actually. I'll look into it.
